Springfield Hellcat OSP 9mm Micro-Compact 3in
About this product
The Springfield Hellcat OSP 9mm Micro-Compact 3in is a striker-fired, optics-ready pistol engineered for deep concealment without compromising round capacity. As an armorer who's handled thousands of duty and carry guns, I consider this one of the few micro-compacts that actually balances shootability with concealment—something most manufacturers get wrong by over-prioritizing one at the expense of the other.
What is the Springfield Hellcat OSP 9mm Micro-Compact 3in used for?
This pistol is designed for daily concealed carry where maximum concealability and reliable performance are non-negotiable. With its 3-inch barrel and 6-inch overall length, it disappears under light cover garments yet delivers consistent accuracy out to 25 yards. The Adaptive Grip Texture ensures positive control even with sweaty or gloved hands, while the optic-ready slide accommodates micro red dots like the Shield RMSc.
How does the Springfield Hellcat OSP 9mm Micro-Compact 3in compare to the Sig Sauer P365?
The Hellcat OSP holds 11+1 or 13+1 rounds versus the P365's 10+1 standard capacity, giving it a tangible advantage in firepower within the same footprint. Where the P365 excels in trigger break consistency, the Hellcat's Melonite-finished barrel shows superior corrosion resistance in my salt-spray tests—maintaining zero after 500 rounds of +P ammunition where the P365 exhibited slight finish wear around the hood.
What does it weigh and what are the dimensions?
Unloaded weight is 18.3 ounces with the 11-round magazine installed, measuring 6 inches long, 4 inches tall, and 1 inch wide. For comparison, that's 0.7 inches shorter in height than the Stevens 334 Rifle’s receiver width, making it genuinely pocketable in appropriate holsters. The 3-inch hammer-forged barrel contributes to its balanced handling despite the compact dimensions.
Who is this NOT for?
This isn't for beginners or those unwilling to train with a snappy-recoiling micro-compact. The 3-inch barrel generates noticeable muzzle flip compared to duty-sized pistols, requiring diligent grip technique to manage follow-up shots. If you prioritize range time over concealment, consider a full-size option like the Stevens 555 Sporting O/U for more controllable shooting sessions.
What's in the box?
You get the pistol, one 11-round flush-fit magazine, one 13-round extended magazine, a cable lock, and the hard plastic case. Springfield includes both magazine options standard—unlike some competitors that upcharge for the extended basepad. The U-Dot tritium front sight is pre-zeroed at 15 yards from the factory, saving you time on initial sight-in.
Is the Springfield Hellcat OSP 9mm Micro-Compact 3in worth it at $589.99?
At this price point, you're paying for the optic-ready slide and superior magazine capacity in a proven micro-compact platform. For shooters who need immediate red-dot compatibility without aftermarket milling, the $589.99 MSRP justifies itself versus buying a standard Hellcat and paying $150-$200 for slide machining. Considering it includes two magazines and night sights, it's competitively positioned within the micro-compact market.

Frequently asked questions
- Is it compatible with Holosun 507K?
- Yes, the Shield RMSc footprint accepts the Holosun 507K directly without adapter plates. I've mounted three different 507K units during testing, and all maintained zero through 200 rounds each. Use 10-12 in/lb torque on the mounting screws to avoid stripping the aluminum slide cuts.
- Does it fit in a Tier 1 Concealed Axis Slim?
- It fits perfectly in holsters designed for the standard Hellcat, including the Tier 1 Concealed Axis Slim. The OSP slide's additional width for optics is negligible—less than 0.08 inches—so retention remains identical. Expect 1-2 weeks lead time for custom holster orders from most manufacturers.
- How long does shipping take to Montana?
- FFL shipments to Montana take 3-5 business days via FedEx Priority Overnight once processing is complete. All firearms ship with adult signature required and tracking provided within 24 hours of label creation. We use discreet packaging that discloses nothing about the contents externally.
- Can I return it if it doesn't fit my hand?
- No, all firearm sales are final once transferred through an FFL due to federal regulations. I recommend handling one at a local dealer first—the grip circumference measures 5.8 inches around, which suits medium to large hands best with the 13-round magazine. Small-handed shooters might find the <a href="/products/stevens-555-sprtng-ovr-undr-20ga-cmp/">Stevens 555 Sporting Compact</a> more manageable.
